The fortified house of Rumlaborg and its turbulent history

The fortified house of Rumlaborg, originally named Humlaborg, is located in Huskvarna in Hakarps socken in Jönköpings kommun. The site was based on a bishop's garden, Humblarum, which was founded in the 1200s or early 1300s. In 1366, Albrekt of Mecklenburg had a fortified house built on the site to protect Västra Holavedsvägen and Östra Holavedsvägen, roads leading toward Östergötland and Danish troops.

During Engelbrekt Engelbrektsson's uprising in 1434, Rumlaborg was defended by Otto Snaps, a knight of Eric of Pomerania. The fortress was burned down by the rebels and was rebuilt in 1448 by Karl Knutsson (Bonde). In 1452, the fortress was besieged by the Danes; the commander Eggert Krummedige chose to side with them, but the fortress was subsequently captured by Eric Nipertz.

In 1464, the fortress was besieged again during Karl Knutsson's renewed takeover and was captured by Kettil Karlsson (Vasa). During the time of Sten Sture the Elder, the fortress was destroyed and fell into disrepair. In the 1930s, the ruin was restored, and archaeological excavations were conducted by Georg Sahlström and the Huskvarna local history society.
